Embodiment 1

[0016] A new type of additive for blue skin rewetting, its composition is: adipic acid 52%, Pingpinga O-15 13%, sodium dodecylbenzene sulfonate 15%, sodium tripolyphosphate 20%, grinding Crush and mix thoroughly. According to the following process, carry out the re-humidification process on the long-standing dry and hard blue skin, and conduct experiments and comparisons with commonly used re-humidity aids such as Pingpingjia, penetrating agent JFC, and degreasing agent.

[0017] The amount of material added is based on the quality of the pigskin shaved wet blue leather

[0018] Rinsing or rewetting Distillation 200% Temperature 32~38℃

[0019] Formic acid (85%) 0.3%

[0020] Rehumidification aid 0.7% 40~60min

[0021] Rinse and check for water return

[0022] The moisture rehydration aid mentioned in the process refers to Pingpingjia, penetrating agent JFC, degreasing agent and the aid of the present invention using the same process for comparison....

Embodiment 2

[0024] A new type of auxiliary agent for rewetting of blue skin, its composition is: mixed acid 46%, Pingpingjia O-20 15%, sodium dodecylbenzenesulfonate 15%, sodium tripolyphosphate 24%, ground and pulverized Mix thoroughly afterwards. Experimental comparison was carried out by the process described in Example 1.

[0025] Example 1-2 See Table 1 for the softness of different rehumidification aids after the rehumidification process.

Abstract

The invention provides a novel auxiliary agent used for blue leather wetting and preventing leather surface explosion and a use method of the novel auxiliary agent. The auxiliary agent contains an organic acid compound, a fatty alcohol polyoxyethylene ether surface active agent, an alkylbenzene sulfonate surface active agent and calcium-magnesium ion chelate. The auxiliary agent is used for the blue leather wetting procedure in a tanning industry and can effectively soften and strengthen the blue leather, chelate the calcium salt and magnesium salt of the derma surface and bath lotion, lead the leather to have soft and smooth hand feeling, assist to prevent the leather surface explosion and particularly have the obvious effects on the long-term change, wetting and strengthening of the blue wet leather.

Description

technical field [0001] The invention relates to the field of a new auxiliary agent for tanning production, more specifically, the invention relates to a new auxiliary agent for rewetting of blue leather and the usage of the new auxiliary agent. Background technique [0002] As a traditional and modern industry, the leather industry is closely related to people's production and life. In order to meet the requirements of the market, tanners have been working hard to improve the quality of leather products. In the process of tanning, the quality of leather is not only related to the quality of raw leather, the quality of leather chemicals used, and the superiority of the process, but also has a lot to do with the mastery and control of each process in the process. [0003] As an important process in the dyeing and finishing part, the rewetting of wet blue leather has an important impact on the quality of the final leather product. Whether the wet blue leather is rewet is suff...
